steveb Posted February 18, 2008 Report Share Posted February 18, 2008 I can't get this working, I've moved my wideband to AN1 with voltage points reversed as (5v as voltage point 1 and 0 as voltage point 2) described (why does it need this doing?), when logging it correlates with my WB gauge so all fine. With CLL OFF the cars fine but if i enable CLL it tries to make it run too lean, I'm only allowing it 10% change from the map as its very close anyway, but for idle for example it goes straight to -10% and takes AFR to 16:1. Altering the dither voltage in the cll menu doesn't make any difference, so any suggestions? thanks Steve Quote Link to comment Share on other sites More sharing options...
ashesman Posted February 18, 2008 Report Share Posted February 18, 2008 A narrow band sensor has a voltage that increases as the engine gets richer. As CLL has to work with both narrow and wideband sensors you need to make you wideband sensor also have a voltage that increases as the engine gets richer (eg 22:1 = 0V (point A), 8:1 = 5V (point ). That will involve recalibrating the wideband sensors output and then changing the ECU to match the output. After that a dither voltage of approx 2.4 volts will give CLL targeting 14.7:1.

steveb Posted February 19, 2008 Author Report Share Posted February 19, 2008 Got it working, thanks for the help. Had to reverse the LC-1 output. Quote Link to comment Share on other sites More sharing options...
